Abstract:
The bulk and grain densities, porosity, water content, and ultrasonic compressional- and shear-wave velocities of 25 basalt samples from DSDP Holes 597B and 597C were measured. The velocities were measured at in situ pore and confining pressures. The bulk densities of the samples vary between 2.690 and 3.050 g/cm**3. Porosities of selected samples vary between 2.4 and 9.3%. The grain densities vary between 2.993 and 3.117 g/cm3, a range that suggests that bulk density differences are due primarily to variations in porosity. Compressional-wave velocities range from 5.70 to 6.81 km/s, and shear-wave velocities range from 1.66 to 3.84 km/s. The variation in compressional velocity appears to be due primarily to variations in grain size and the associated greater density of grain-boundary cracks for samples with a smaller average grain size. On the basis of these results we would expect compressional and shear velocities to increase with increasing depth in the shallow crust, primarily as the result of the effects of confining pressure on crack density.
